After a few weeks of chasing out various electrical gremlins associated with a car that's sat most of its life, I discovered that the turn signal switch was bad.

None of my turn signals worked -

Per Service Manual I checked the fuse (good); replaced flasher with a good known one; checked for power at the flasher from the fuse block; checked continuity between the other flasher tab and the orange wire at the switch.

So I called Fusick to get a new switch but they're backordered...

I decided to see if I could fix it - and I did..and saved $65!

HERE"S HOW: -

Step 1 - I Carefully bent back the tabs to separate the plastic housing from the metal mounting bracket. BE CAREFUL - there are 4 ball bearings that will drop out (ask me how I know).




Step 2 - Open and Inspect - my contacts were dirty, grooved, and the grease was essentially solidified.


Step 3 - I used some emery paper to file down the contacts to a level surface - after I was happy with them I cleaned everything with CRC QD Electronic Cleaner




Step 4 - I used dielectric grease on all contacts and moving parts and reassembled - the ball bearings go into little grooves at the base of the interior plastic switch and roll between the switch and the metal bracket - I used a small pair of C-clamps to help hold everything together while I re-bent the tabs into place.





Now it works like new as do my turn signals! This switch is the same for 56-62 (non F-85) so hopefully this will help someone out!

What an awesome post! I'm having issues with my brake lights and turn signals on my '62 working strangely and suspect the turn signal circuit switch as the culprit. I was going to replace it but now thinking I may give your repair method a shot. Thanks for such a detailed post about this!
